Red Bull RB8 Launch

I think one of the BBC commentators last year commented on how the exhausts had to come out of the bodywork, and suggested that they had a tractor exhaust that pointed straight up

Which would produce a downward thrust pushing the car to the ground......
And this is why FIa needs to back off of the exhaust regs. They will never stop teams from taking advantage....If anything they are driving up cost with teams spending overtime trying to igure out clever solutions weak in and out. If the ban was lifted the teams with start the season with 90-100% efficiecny of the system and never look back

If you've read Scarbs explanation of the exhausts, there are a variety of ways in which you can gain benefit from the exhausts whilst not aiming them directly at anything. Just below the wing or on the outside of the wing end plate for instance. This is no more legal (in the spirit of the regulations) than directly blowing the surface.

They need to either allow the teams to use the gases how they want or force a set location, direction and shape as stated before. They also need to stop writing rules with the knowledge of it creating these grey areas, the FIA trust the engineers too much!

These exhausts blowing towards the rear wing, slightly reminiscent of the 1999 Ferrari, which had the exhausts out of the top of the sidepods, pointing at the rear wing.

I can't remember offhand the pros and cons of the F399's system but perhaps Red Bull are going for a similar approach.
